5. Improving Your Omega-3/Omega-6 Ratio . Many of you know that some of our standard plant-based oils, such as sunflower, are high in omega-6's and can lead to inflammation. Flaxseed is completely different, however, as it is packed with alpha-linolenic acid, which your body converts into the all-important omega-3's DHA and EPA. Many guys feel noticably better when consuming flaxseed and this is probably the reason why. Our bodies were meant to consume a very low omega-6 to omega-3 ratio - Dr. Greger says 4:1 is probably the safe maximum - and flaxseed can help you greatly improve this ratio.
Other significant adverse effects of testosterone supplementation include acceleration of pre-existing prostate cancer growth in individuals who have undergone androgen deprivation; increased hematocrit , which can require venipuncture in order to treat; and, exacerbation of sleep apnea .  Adverse effects may also include minor side-effects such as acne and oily skin, as well as, significant hair loss and/or thinning of the hair, which may be prevented with 5-alpha reductase inhibitors ordinarily used for the treatment of benign prostatic hyperplasia , such as finasteride .  Exogenous testosterone may also cause suppression of spermatogenesis , leading to, in some cases, infertility.  It is recommended that physicians screen for prostate cancer with a digital rectal exam and prostate-specific antigen (PSA) level before starting therapy, and monitor PSA and hematocrit levels closely during therapy.
